1. Treating Contaminants Of Emerging Concern In A Variety Of Water Sources 8/13/2020

   Contaminants of emerging concern (CECs) can be a challenge throughout all stages of the water cycle. Here are some key considerations for water treatment plants (WTPs), wastewater treatment plants (WWTPs), and water reuse applications where removal of 1,4-dioxane or per- and polyfluoroalkyl substances (PFAS) is currently, or might soon become, a mandatory focus in their treatment train.

2. Saving Our Reservoirs From Invading 'Cling-Ons' 8/13/2020

   Like a page out of a science fiction novel, a wave of aquatic invaders is trying to discretely slip into the nation’s reservoirs and lakes.

3. Planning For Total Resiliency In Fighting Contaminants Of Emerging Concern 8/12/2020

   In the constant flow of drinking water and wastewater treatment systems, operators have precious little time to skip a beat. When unexpected changes arise — such as being mandated to reduce contaminants of emerging concern (CECs) — the ability to maintain balance throughout the treatment process becomes a driving factor. For decision-makers faced with remaining resilient despite CEC concerns, here are some key points to consider.

4. Use Of Tear Gas In Protests Leads Portland Regulators To Conduct Stormwater Tests 8/12/2020

   Recent riot control methods to quell protests in Portland, Oregon, have led some regulators to raise concerns about potential source water contamination.

5. Fight Contaminants Of Emerging Concern With A Pipeline Of Innovation 8/11/2020

   Water treatment challenges are never-ending — from source water availability, to seasonal upsets, to new contaminants of emerging concern (CECs). The best way to stay ahead of such issues is to cultivate a pipeline of innovative solution development ready to address the next challenge. Here are some key insights for evaluating suppliers that are best positioned to do exactly that.

6. NY Approves First-Ever Limit For 1,4-Dioxane In Drinking Water 8/11/2020

   New York has become the first state in the country to adopt a drinking water standard for the contaminant 1,4-dioxane, which has been found at high levels in some of its public supply wells. It also adopted stricter limits for some of the country’s most pernicious drinking water contaminants, meaning that treatment systems in the state will have a significantly larger burden in getting effluent up to snuff.

7. Testing Better Paths To Contaminant Control 8/10/2020

   As a utility, it is tough enough to be notified that you need to remove a new contaminant of emerging concern (CEC). It’s even harder without having a complete picture of what is involved. For water treatment plants (WTPs) and wastewater treatment plants (WWTPs), here is how choosing the right testing regimen is essential to quantifying the degree of the problem and evaluating the optimum treatment alternatives.

8. Get Ready For An ISO 9001 Audit 8/10/2020

   Audits often trigger anxiety, especially when conducted by a second or third-party. They are also time and effort-consuming, which is why companies question whether audits such as the ISO 9001 audits are worth the hassle.

9. Clarifying 'Precision' With Circular Clarifier Drives 8/10/2020

   The thousands of circular clarifier mechanisms that have been a key component in our domestic treatment plants for generations create a large market for new, replacement, and rehabilitation of drive mechanisms. Not surprisingly, several of the manufacturers who produce these specialty drive assemblies compete for their share of the market in just about every way they can think of — one of which is touting the virtues of their drive units.

10. Managing Your Potable Water System During The Pandemic 8/10/2020

    The government mandated business closures and travel restrictions, due to the COVID-19 virus, have caused many businesses to reduce water flow in various complex building water systems. While the COVID-19 virus is not associated with building water systems, there are other pathogens and water quality issues that can potentially develop due to stagnant or reduced water flow in buildings.
